+{# 
+   This template overrides the quantecon_book_theme layout to fix the Jupyter Book link
+   from https://jupyterbook.org/en/stable/ to https://jupyterbook.org/v1/
+   
+   Unfortunately, the theme doesn't provide a more granular block to override just the
+   footer link, so we need to override the entire 'content' block. This is the minimal
+   change required to fix the redirect issue reported by the link checker.
+   
+   The only modification from the parent template is on line 89:
+   - OLD: <a href="https://jupyterbook.org/en/stable/">Jupyter Book</a>
+   + NEW: <a href="https://jupyterbook.org/v1/">Jupyter Book</a>
